The Washington Business Journal published its 2026 list of the 75 fastest-growing companies in Greater Washington last week, and 11 of them have a Reston or Herndon address. Six are in Reston and five are in Herndon. McLean, the most common address on the list, also has 11.

The local group runs from an 82-person general contractor on Park Center Road to Carahsoft, the Reston company that reported $21.9 billion in revenue last year reselling technology to government buyers. Eight of the eleven count federal agencies among their core customers, and four sell cybersecurity in one form or another. The three without federal work at their core are a builder with a data center practice, a marketing software company for car dealers, and a firm that backs up corporate data and restores it after an attack. Across all 75 companies, the Business Journal counted roughly two dozen government contractors that kept growing through what it called one of the most turbulent years the federal market has seen.

WBJ ranks companies on two years of revenue growth

The list covers privately held companies headquartered in the region and ranks them on revenue growth from 2023 to 2025. To qualify, a company needed at least $2 million in revenue in 2023, at least $10 million in 2025 and an increase in each year. Private equity backing is allowed, but subsidiaries of other companies are not. The percentage beside each name averages two annual growth rates, 2023 to 2024 and 2024 to 2025, rather than measuring the total change across both years.

TRINITY Group Construction, the highest-ranked local company at No. 5, carries an 82 percent growth rate on the list, yet its revenue nearly tripled over the period, from $87.4 million in 2023 to $257.3 million in 2025. Navstar’s revenue rose 83 percent in 2024 and 7 percent in 2025, and the list averages those two years into the 44.9 percent beside its name.

Four of the eleven sell cybersecurity

GuidePoint Security (No. 28, Reston) is the largest of the four by a wide margin, with $3.0 billion in 2025 revenue and 1,275 employees. Michael Volk founded it in 2011. The company consults on security and resells security products to more than 5,900 organizations, a client list it says includes every cabinet-level federal agency. In June 2025 GuidePoint moved its global headquarters from Cooperative Way in Herndon to 1900 Reston Metro Plaza, the office building at Comstock’s Reston Station next to the Wiehle-Reston East Metro stop. Scott Rachford became CEO in July 2026, and Volk moved to executive chairman.

ShorePoint (No. 36, Herndon) works only for federal agencies. Matt Brown co-founded it in 2017, and most of the revenue it earns on contracts held directly with an agency comes from the Treasury Department, including the IRS and the Bureau of Engraving and Printing. The firm handles zero trust programs (a design that treats every user and device as unverified until it proves otherwise), security data and analytics, and penetration testing, in which a hired team attacks a client’s systems to find the weak points first. The private equity firm CM Equity Partners invested in ShorePoint in November 2025. The company says 2025 was its fourth straight year on the list.

Hypori (No. 16, Reston) gives a soldier or federal employee a virtual phone that runs in a secure cloud and streams to the person’s own handset, so government data never lands on the personal device. The Army, Air Force and Space Force all use it, and in April 2026 the Air Force expanded its program from 10,000 licenses to 17,000. The company began as a startup called DroidCloud and took its current form in 2021. Hypori’s revenue roughly doubled over the two years, from $14.5 million to $29.7 million, on growth of 48 percent in 2024 and 39 percent in 2025. Carahsoft, another Reston company on the list, joined a Hypori funding round in January 2025.

Assured Data Protection (No. 18, Herndon) sells mainly to businesses rather than agencies. Its work is backup, disaster recovery and cyber recovery, which means getting a company’s systems and data running again after an outage or a ransomware attack. Its founders started the company in 2016 in Leeds, England, and Virginia, and the British private equity firm Oakley Capital agreed to buy it in October 2024. In June 2026 the data security company Rubrik named Assured its global managed service partner of the year. A managed service provider, or MSP, runs a piece of another company’s technology for it on contract. Its growth sped up in 2025, from 39 percent to 45 percent.

Five more run on federal IT contracts

Carahsoft Technology (No. 61, Reston) has the lowest growth rate of the local eleven, at 18.9 percent, and by far the largest revenue. Craig Abod founded the company in 2004. Federal, state and local agencies and school systems buy software and cloud services through Carahsoft from more than 1,000 technology vendors, which makes it what the industry calls an IT aggregator, a middleman that holds the government purchasing contracts so each vendor does not have to. Its revenue rose from $18.9 billion in 2024 to $21.9 billion in 2025, an increase of about $3 billion in one year, roughly GuidePoint’s entire 2025 revenue. Carahsoft lists 4,210 employees and has its headquarters on Sunset Hills Road.

Dev Technology Group (No. 52, Reston) has worked out of 11440 Commerce Park Drive since its founding in 1998, and in 2023 it leased another 10,000 square feet there. The company builds software, data systems and biometric tools for homeland security, State Department and defense agencies. In October 2026 it announced a five-year, $22 million Department of Homeland Security contract for a mobile language translation app. Dev Technology reported $136.3 million in 2025 revenue and 364 employees.

Amivero (No. 43, Reston) shares a building with GuidePoint at 1900 Reston Metro Plaza. Olivia Trivisani Bowker founded it in 2018, and its AI, data and automation work goes mostly to Homeland Security agencies, including Customs and Border Protection, Immigration and Customs Enforcement and Citizenship and Immigration Services. Revenue grew from $26.2 million in 2023 to $41 million in 2025. In September 2026, after the period the list measures, Xpect Solutions acquired Amivero, and the Business Journal notes the sale beside its entry.

Navstar (No. 15, Reston) has been run by Joanna Alexis since she founded it in 1999, and its offices are on Campus Commons Drive. Navstar handles data, cloud and cybersecurity work for the intelligence community and the State and Treasury departments, sometimes as the prime contractor, the firm that holds the contract with the agency, and sometimes as a subcontractor working under one.

Centurion Consulting Group (No. 32, Herndon) is the smallest of the local eleven by revenue, at $15.8 million. Founded in December 2016 and led by principal owner Theresa Zandi, the woman-owned firm supplies IT staff and consultants to federal agencies including the Census Bureau, the Social Security Administration, the National Institutes of Health and the IRS, often as a subcontractor, along with commercial and state clients. Centurion also made the list in 2021, at No. 29.

A builder and a car-dealer software company sell to the private sector

TRINITY Group Construction (No. 5, Herndon) ranks highest of the eleven local companies. The firm has worked since 2002 and builds commercial interiors, multifamily housing, base building work (the structure, shell and core systems of a new building) and mission-critical facilities, the industry’s term for data centers and other buildings that cannot go offline. TRINITY says it has built more than 3 million square feet of data center infrastructure, including work for Equinix in Dulles. The company lists 82 employees. A general contractor’s revenue includes the cost of the subcontractors it hires, which is how a staff of 82 can bill $257.3 million in a year. Most of TRINITY’s growth came in 2024, when revenue jumped 144 percent, and the 2025 gain was 20 percent. KiNRG, a clean energy and hydrogen company, bought TRINITY in a deal that closed April 1, 2026. Mil “Flip” Wallen III remains CEO.

Team Velocity (No. 22, Herndon) sells software to car dealers. Its Apollo platform runs dealership websites, digital advertising, an AI assistant and service reminders that bring past buyers back for maintenance, and the company says roughly 3,000 dealerships use it. Co-founder and CEO David Boice built an earlier auto marketing firm, AutoMark, and sold it to Reynolds and Reynolds in 2000. In May 2026 Team Velocity bought Foundation Direct, a digital ad agency started by former Google auto executives, and entered Canada through General Motors of Canada. With $330.3 million in 2025 revenue and 583 employees, it is the third-largest local company on the list, behind Carahsoft and GuidePoint. Team Velocity ranked No. 34 a year ago.

Most of the eleven grew more slowly in 2025 than in 2024

Because the ranking allows no down years, every company on the list grew in both 2024 and 2025. At least eight of the local eleven grew more slowly in the second year than the first. Assured Data Protection and Amivero sped up. The biggest drops belonged to the fastest risers: TRINITY went from 144 percent to 20 percent, and Navstar from 83 percent to 7 percent. Team Velocity grew 44 percent and then 32 percent, and Dev Technology 26 percent and then 18 percent.

The list stops at December 2025, so none of its figures reflect 2026.

Two of the companies share a building, and four Herndon firms sit outside the town

GuidePoint and Amivero both list suites at 1900 Reston Metro Plaza, at Reston Station. Carahsoft is about half a mile west on Sunset Hills Road, on the same north side of the Dulles Toll Road. Dev Technology and Navstar are just across the toll road on its south side, within a short walk of the Wiehle-Reston East station’s south entrance, and Hypori is less than a mile east of Navstar on Robert Fulton Drive.

Of the five Herndon companies, only ShorePoint, on Worldgate Drive, has an address inside the Town of Herndon. TRINITY and Assured Data Protection are near neighbors on Park Center Road, and Team Velocity and Centurion sit around the corner from each other on Sunrise Valley Drive and Coppermine Road. Those four carry Herndon mailing addresses in the 20171 ZIP code, but their offices are in unincorporated Fairfax County. Homeowners inside the town limits pay a Town of Herndon real estate tax on the same bill as the county’s, while homes in 20171 outside the town pay the county’s tax alone.

The eleven report more than 7,300 employees, though not all of them work here

That headcount covers each company’s full workforce, and Carahsoft alone accounts for 4,210 of it. Some of those employees work at other offices or remotely, and the list does not break out how many report to a desk in Reston or Herndon.
